Monkey Slug

Dear Curious,
This is a Monkey Slug Caterpillar,
Phobetron pithecium, and in its adult form it is known as a Hag Moth.  BugGuide has this interesting description:  “Caterpillar is most frequently seen. Bizarre, brown, hairy creature that resembles some sort of aquatic creature more than a caterpillar. Three pairs of long arms and three pairs of short arms, which are ‘deciduous’ – often one or more is missing.”  Exercise caution when handling the Monkey Slug as it is one of the Stinging Caterpillars in the family Limacodidae.
